The for iteration in range(max_iterations) loop up top made me look for a cap on the fix-test-fix cycle specifically, and I don't see one beyond that outer limit. Worth separating the two. An agent that can reason "still failing after 3 edits, my understanding is wrong, stop and report" is a harder capability than just not exceeding the overall budget. Right now the model has to decide that on its own from the prompt instruction alone. Is a bounded-retry-with-escalation rule coming later, or is that intentionally left to model judgment for now?
